dockerfile

COPY XXX.jks /var/lib/XXX.jks

yaml文件：

apiVersion: batch/v1beta1

kind: CronJob

metadata:

spec:

  schedule: "*/30 * * * *"   // 每隔30分钟执行一次

  jobTemplate:

    spec:

      template:

        spec:

          imagePullSecrets:

            - name: XXXXXXXXX-key    // pull image的时候，需要认证

          containers:

          - name: imagedownload

            image: 私有image仓库的地址/imagedownloadjob:259

            env:

              - name: DB_HOST

                value: "XXXXXXX"

          restartPolicy: OnFailure

过程：

1: 在工程目录下： mvn clean pcage -P dist // 打包，安装POM中定义的dist的方式进行打包

2: 创建docker 镜像：

　　　docker build -t url/forecasting/imagedownloadjob:196 --compress --force-rm --build-arg VERSION=196 --build-arg MICROSERVICE=job.imagedownloadjob --build-arg REPOSITORY=url/forecasting/imagedownloadjob .

( -t, --tag list Name and optionally a tag in the

--compress Compress the build context using gzip

--force-rm Always remove intermediate containers

--build-arg list Set build-time variables)

3: 推送docker镜像到私有仓库之前，先要登录一下docker仓库 docker login URL

把docker镜像推到私有仓库：

docker push url/forecasting/imagedownloadjob:196

通过pull命令验证是否推送成功
docker pull url/forecasting/imagedownloadjob:196

4： kubectl create -f cronjob.yaml //创建job

kubectl get cronjob hello //查看job状态

kubectl get jobs --watch // 查看

kubectl describe pod fail-1036623984-hxoas // 查看pod失败的原因

kubectl delete cronjob hello //删除cronjob

使用kubectl delete jobs –all可以删除当前namespaces下所有的job
